Cable-TV giant Nickelodeon has expressed interest in being part of developer Thor Equities’ $2 billion plan to turn the famed summer amusement area’s rundown strip into a glitzy year-round playground and public attraction, sources said.

Nickelodeon’s parent company, Viacom, is talking with Thor about the possibility of the kids network operating a theme hotel on part of the 3.1-acre Astroland amusement-park property the developer purchased last week.

Such a plan would resemble Nickelodeon’s pitch for Governors Island, which city and state officials shot down last month. That plan also included an indoor water park, but it was unclear whether the water park has come up again in preliminary talks with Thor.

Thor spokesman Lee Silberstein said companies are interested in Coney Island “now that there is a serious proposal for the area’s revival.”

Nickelodeon Senior VP Howard Smith said, “We think a Nickelodeon-themed family resort hotel would be hugely popular with New Yorkers.”
